to which any architectural design can arrive. It took its rise in that happy soil of Attica,,

capital, which being first executed at Corinth, received its name from thence. It appears that
the members and mouldings of the entablature had no other institution than what was already-
establissied in the nature of tilings sor the Doric and Ionic modes {b) -, the Corinthian modilions,
though disserently proportioned, ornamented, and disposed, answer to the Doric mutules, and
